TTTTTD JAMES S. DUFFY, OF PEORIA, ILLINOIS.

LEVEL.

ressent.

To all ifi/om 'it may concern Be it known that I, JAMES S. DUFFY,citizen of the United States, residing at Peoria, in the count-y ofPeoria and State of Tllinois, have invented certain new and usefulTmprovements in Levels, of which the following is a specification.

This invention relates to improvements in levels, and particularly tothat type of device used by carpenters, mechanics and other workmengenerally.

The principal object of my invention is the provision of a device ofthis character which is small in compass and may be readily attached toand detached from larger instruments with which it is adapted to beused, as for instance a straight-edge or square.

A further object is the provision in such a device of means for readilyadjusting the same and means whereby the same may be attached in acorrect position.

To the accomplishment of the foregoing and such other objects as mayhereafter appear, my invention consists in the construction, combinationand arrangement of the parts and details hereafter described and soughtto be defined in the appended claims, reference being had to theaccompanying drawings forming a part hereof and which show merely forthe purpose of illustrative disclosure preferred embodiments of myinvention, it being understood however, that various changes may be madein the construction and arrangement of the parts and details within thesco-pe of the appended claims without digressing from my inventive idea.

ln the drawings: Figure l is a side elevation of one form of my device.Fig. Q. is an end view of Fig. 1. Fig. 3 is a view similar to F ig. l,but shows a slightly modilied form of my invention. Fig. 4 is an endview of Fig. 3. Fig. 5 is a view on a smaller scale, of my deviceapplied to a straight edge. Fig. 6 represents one form cf my inventionapplied to a square.

Tn the description like numerals and characters of reference are usedto'designate like and corresponding parts.

The forms of level vnow in general use are objectionable to the artisanfor the reason that they take up too much room in his tool bag or box,and further provide an additional weight for him to transport.

My idea broadly considered is to provide Specification of LettersPatent.

Serial No. 676,726.

a level of small size and light weight with an accompanying attachingmember having a straight edge by which the level may be used inconnection with any straight edge or other similar implement and readilydetached therefrom for other use. This device may readily be attached toa square, for instance.

The preferred form of my invention is shown in Figs. l and 2 wherein thenumeral l designates the tube which has one end closed and the other oneprovided with a screw threaded plug 2. This tube has the open portion 3in which is displayed the glass tube l which contains the usual liquidand bubble. This metallic body l is provided with the extensions 5through which pass the adjusting screws 6. The lower edge 7 of the bodyportion lis a true straight edge. To the sides of the lower portion ofthe body of this instrument are attached the frictional gripping members8, which in this form of the device are elongated, resilient, metallicmembers. These members provide a ready means of attachment for thedevice to the article with which it is to be used. For instance, if usedwith a square, then spring members 8 are slipped over one arm thereofand hold the level thereon by the frictional engagement. If however thedevice is to be used with a brick layers or carpenters straight edge forinstance, an attaching means for a straight edge is necessary. Thisattaching means is in the form of a bar 9 having an upper straight edge10 and a lower straight edge ll. Projecting laterally and horizontallyfrom the lower edge are the feet 12 having the down turned vertical ears13 which are provided with the elongated slots llt as shown. This member9 is attached to a straight edge by means of screws or similar meanspassing through the slots 14 and positioned in either a horizontal orvertical position so that the straight edge may be used in eitherposition. The level itself may be readily positioned on member 9 andheld securely thereon by means of the gripping members 8. Of course anynecessary adjustment may be made by means of the screws 6.

The other form of my device illustrated in Figs. 8 and 4t issubstantially the same. Tt has the body portion 20 having the upwardlyextending arms 2l between which is secured the spirit level tube 22having the opening 23 and ordinary glass tube 24:. This tube has theremovable ends 25 and is held in adjusted position between the arms 2lby means or" the screws 26. The body portion has the lower straight edge27 and is provided with spaced pairs ot resilient gripping members 28which are located somewhat near the ends of the body portion as shown.The attaching member 9 is the same as that previously described.

The object and use of my invention has been fully described and isbelieved to be clear and sutlicient.

It is seen that I have provided a level which may be readily attached toand detached from a straight edge and which may be used in connectionwith a Square or similar device. This will be a special benefit for theartisan who carrieshis own kit of tools in that it economizes space andweight.

The construction is simple and the device is neat and attractive inappearance. The adjustment is simple, in case that is necessary.

l/Vhat I claim is l. In a device of the character described, a bodyportion including a spirit level and a bottom portion, said bottomportion of the body having its lower edge straight and having endextensions, resilient members secured to the opposite sides of saidbottom portion of the body, said resilient members providing meanswhereby the device may be detachably mounted on an article and adjustingmeans mounted in said end extensions, whereby the device may be adjustedin proper relation to the article on which it may be mounted.

2. In a device of the character described, and in combination, a bodyportion including a spirit level and having a lower straight edge, andan attaching member having an upper straight edge with means forattaching said member to various instruments, and frictional grippingmembers attached to said body portion and adapted to engage saidattaching member so as to hold the spirit level on the attaching member.

3. In a device of the character described, and in combination, a bodyportion including a spirit level and having a lower straight edge, anattaching member having an upper straight edge and having attaching earsor feet whereby it may be attached to instruments, said body portionhaving resilient metallic members on opposite sides of its lower portionin opposed relation, which are adapted to frictionally engage theattaching member and hold the level thereon.

e. In a device oi the character described, and in combination, a bodyportion including a spirit level and having a lower straight dge,4 andan attaching member having an upper straight edge with means forattaching said member to various instruments, and a plurality ofresilient frictional gripping members attached to said body portion andadapted to engage said attaching member so as to hold the spirit levelon the attaching member, with said straight edges in opposition, andmeans for adjusting the level relative to the attaching member.

5. In a device of the character described, and in combination, a bodyportion including a spirit level and having a lower straight edge, andan attaching member having an upper straight edge with means forattaching said member to various instruments, and a plurality ofresilient frictional gripping members attached to said body portion andadapted to engage said attaching member so as to hold the spirit levelon the attaching member, with said straight edges in opposition, saidbody portion having extensions, and screws adjustably mounted in saidextensions and adapted to bear on said attaching member whereby thelevel may be adjusted relative thereto.

6. In a device of the character described, and in combination, a bodyportion including a spirit level and having a lower straight edgeextending approximately the length of the body portion, an attachingmember having an upper straight edge and having means whereby it may bedetachably connected to various instruments, said body portion havingresilient metallic members on opposite sides of its lower portion inopposed relation, which are adapted to frictionally engage the attachingmember and hold the level thereon.

In testimony whereof I aiiix my signature, in presence of two witnesses.
